Sterling Accord bathtub, installation with pictures

I am looking for an inexpensive update for my condo bathroom. I purchased the Aquaglass Eleganza, but the surround was cracked. When I looked online to see if my Lowe's had another in stock, the reviews caught my eye. They were horrible, particularly for the tub. 68 out of 69 reviews said the tub cracked in less than a year. So, when I return the cracked surround I'll be leaving the tub in the store, too. I looked at the Sterling Accord at the depot, but I can't find any reviews for this product. Does anyone have any knowledge or first-hand experience with this tub/shower surround? Thanks!

It says it is caulk-less and the pieces just snap together. I'm nervous about it leaking. Part of the reason for this update is that the old tub/shower leaked resulting in a hole in my living room ceiling. Does it really work without caulk? If you caulk it, will that cause any kind of damage to the product? Thanks so much for your help! This has caused me a lot of angst, so I really appreciate the advice.
